David Geary demonstrates how Java developers implement singletons, with code examples for multithreading, classloaders, and serialization using the Singleton pattern. He concludes with a look at implementing singleton registries in order to specify singletons at runtime. ...
In today’s post, we’ll learn how to implement singleton classes in JavaScript using the simplest way. ADVERTISEMENT Singleton Implementation in JavaScript In programming languages like Java, one object can have multiple instances. But when we want to restrict only a single instance of an object...
Getting into the right mindset is incredibly important if you want to write clean code. One requirement is that you should care enough to learn about the business you're writing code within. If we don't care about the domain enough to understand it, then how can we be sure we're using...

C# Socket unable to write data to transport connection C# Socket.IOControl ignoring keepAliveTime / KeepAliveInterval configuration C# specify array size in method parameter C# split string (",") --error...

Yes. Always try to make state objects singletons. 5.3. Advantages of state design pattern? We can easily add new states and new behaviors in the application without impacting other components. It also helps in reducing complexity by reducing the use of if-else statements or switch/case conditio...
Dagger 2- the library developed by Google Inc. as a fast dependency injector for Android. It helps developers implement a Dependency Injection pattern which is “Inversion of control specific form”. Check out Kotlin + Dagger2 example below. ...
Now, how would we implement this asynchronously using the APM pattern? Something like this:Copy public IAsyncResult BeginCopyStreamToStream( Stream source, Stream destination, AsyncCallback callback, object state) { var ar = new MyAsyncResult(state); var buffer = new byte[0x1000]; Action<...
I used the singleton design pattern to create a class of which there is always exactly one instance. The static reference ensures that one instance is created automatically by the time I first need to use it, and the private constructor ensures that no more instances can be erroneously created...
The pace of exome and genome sequencing is accelerating, with the identification of many new disease-causing mutations in research settings, and it is likely that whole exome or genome sequencing could have a major impact in the clinical arena in the rel
